In a statement released on Thursday evening, the ministry said it had sent a letter to Facebook Ireland Ltd, the company's main global business unit, in response to an April 10 letter from the company's head of data protection.

Facebook is accused of allowing UK-based data company Cambridge Analytica to harvest the personal details of more than 50 million users without their permission to target them during the 2016 U.S. presidential election and the Brexit referendum, Xinhua reported.

Earlier this week, Facebook said in a statement that it was "committed to improving the way we protect people's information, and to providing a safe and secure experience for the more than 115 million Indonesians on Facebook". Facebook Deputy Chief Privacy Officer Rob Sherman claimed Cambridge Analytica requested the data to be used in a certain way, and in their systems.

European Parliament on Wednesday renewed its call to Zuckerberg to come before the Parliament to answer questions on the misuse of European citizens' personal data.

The fact that PwC found no issues raised red flags for privacy advocates.

Chester said the audit shows that the "FTC can not be relied on to really protect consumers". Senator Richard Blumenthal now wants the FTC to consider evidence that Facebook violated their 2011 consent decree and is pushing for stronger oversight. Any violations of that pact could cost the company a ton of money.

The agreement requires that Facebook users give "affirmative express consent" any time that data they haven't made public is shared with a third party. Later, they went on to sell the data which Facebook had no control over.

EPIC chief Marc Rotenberg told Wired: "After Cambridge Analytica, PricewaterhouseCoopers, on behalf of Facebook, reported to the FTC that privacy compliances at Facebook were fine and there were no problems".

Specifically, auditors say Facebook's analysis of privacy risk and efforts to protect user data in the period dating from February 2015 to February 2017 were adequate. The agency is looking at whether Facebook has engaged in "unfair acts" that cause "substantial injury" to consumers.
